6. Sunwarrior Collagen Peptides Building Powder – Best Vegan Option
- The Collagen Building Protein Peptides is not a collagen. Collagen Building Protein Peptides means that the product contains the same set of amino acids and nutrients that your body needs to produce its own collagen. Peptides are created when the amino acids undergo a process called hydrolysis to break them down into shorter chains/smaller molecules, which makes them easier for your body to absorb.
- Plant-based amino acids and peptides are collagen precursors, which are nutrients that your body converts efficiently into collagen. Our beauty-enhancing formula also contains strengthening and supporting nutrients such as vitamin C, trace minerals, leafy greens, silica, and biotin. Hydrating compounds such as hyaluronic acid and tremella mushroom extract attract and retain skin moisture.
- Our Silica is sourced from bamboo, silica is a key co-nutrient for collagen and elastin production. It also boosts calcium absorption to strengthen bones, hair, skin, and nails. The source of Vitamin C in the Collagen Building Protein Peptides is from organic amla also known as Indian Gooseberry as well as from organic sea buckthorn berries. These two fantastic sources provide 10 times the potency of vitamin C in oranges.
- This product has a full amino acid profile, BCAAs, MCTs, and is high in vitamin C. It contains biotin, hyaluronic acid, probiotics, and 100% vegan collagen building ingredients, and it tastes amazing. It has no chemicals or artificial ingredients. It has no added sugar, no dairy, no soy and is gluten-free, Non-GMO, and vegan.
- Sunwarrior's Collagen Builder provides all the amino acids and nutrients that a body needs to naturally make that conversion. Collagen is made primarily of three amino acids: proline, hydroxyproline, and glycine, which gives it unique functional properties different from all other proteins. This also makes it the most important structural protein in the body.
A plant-based collagen-boosting powder that supports the body’s own collagen production using vitamin C, silica, and botanical extracts rather than animal-derived collagen.
Sunwarrior takes a different approach by providing plant-based nutrients that stimulate the body’s natural collagen synthesis rather than supplying animal collagen directly. The formula includes vitamin C, hyaluronic acid, biotin, and tremella mushroom to support nail and skin health from a vegan-friendly source. This is an excellent option for those following a plant-based diet who still want to support nail strength. The powder mixes well into smoothies and has a mild natural flavor.
- Pros:
- 100% plant-based and vegan-friendly
- Includes vitamin C, biotin, and hyaluronic acid
- No animal-sourced ingredients
- Cons:
- Indirect collagen support rather than direct collagen peptides
- May take longer to show results compared to animal-based collagen

How to Choose the Best Nail Strengthening Supplement
The most effective nail supplements contain biotin (vitamin B7), which is the only supplement ingredient with clinical evidence supporting improved nail strength. Studies suggest 2,500–5,000mcg daily can improve brittle nails within 3–6 months of consistent use. Look for supplements that include biotin alongside other supporting nutrients for the best results.
Collagen peptides, particularly Type I collagen, provide amino acids that serve as building blocks for keratin — the structural protein nails are made of. Multi-type collagen formulas that include Types I, II, and III offer the broadest support for nails, skin, and connective tissue. Hydrolyzed collagen is preferred because it’s broken down into smaller peptides for better absorption.
Form matters based on your lifestyle. Capsules offer convenience and precise dosing, powders provide the highest collagen doses per serving and mix into beverages, and gummies make daily supplementation enjoyable but typically contain lower active ingredient amounts. Choose the form you’ll actually take consistently, since nail supplements require 8–12 weeks of daily use before visible results appear.
Third-party testing and GMP certification ensure product quality and label accuracy. Look for supplements that list specific ingredient amounts rather than proprietary blends, and check that biotin doses fall within clinically studied ranges. Supporting nutrients like vitamin C, zinc, and iron enhance the effectiveness of biotin and collagen supplements.
Frequently Asked Questions
What supplements strengthen nails the fastest?
Biotin (vitamin B7) has the most clinical evidence for improving nail strength, with studies showing improvement in brittle nails at doses of 2,500mcg daily. However, results typically take 3–6 months of consistent daily use since nails grow slowly — about 3mm per month for fingernails. Combining biotin with collagen peptides may accelerate results by providing both the metabolic support and structural building blocks nails need.
How much biotin should I take for stronger nails?
Most clinical studies used 2,500mcg (2.5mg) of biotin daily and found improvement in 63% of participants with brittle nails. Higher doses of 5,000–10,000mcg are commonly sold but haven’t been proven more effective. The adequate intake for adults is only 30mcg, but therapeutic doses for nail health are significantly higher. Biotin is water-soluble, so excess amounts are typically excreted without toxicity.
Does collagen really help nails?
Collagen provides the amino acids proline, glycine, and hydroxyproline that the body uses to produce keratin, the protein nails are made of. Some clinical studies have shown that collagen peptide supplementation can increase nail growth rate by 12% and decrease nail breakage by 42% over 24 weeks. Hydrolyzed collagen peptides are preferred because they are broken down for better absorption.
Can I take biotin and collagen together?
Yes, biotin and collagen work through different mechanisms and complement each other well. Biotin supports the metabolic enzymes involved in keratin production, while collagen provides the raw amino acids needed to build nail structure. Many nail supplements combine both ingredients in a single formula for this reason.
Are there any side effects of nail supplements?
Biotin and collagen supplements are generally well tolerated. High-dose biotin can interfere with certain lab tests (thyroid panels, cardiac troponin), so inform your healthcare provider if you’re supplementing. Collagen supplements sourced from shellfish may trigger allergic reactions in those with shellfish allergies. Some users experience mild digestive discomfort when starting collagen supplements.
How long does it take for nail supplements to work?
Most people notice improvements in nail strength and reduced breakage within 8–12 weeks of consistent daily supplementation. Full results, including visibly stronger and faster-growing nails, typically appear at 3–6 months. Fingernails take about 6 months to fully regrow, so patience and consistency are essential.
